LAMP-HOLDER.

Specification of Letters Patent.

Patented Mar.

Application filed March 3, 1919. Serial No. 280,441.

To all whom it may concern:

e it known that we, W'ILLIAa-i' t l-turn and ANTON lV. Srnrn, citizensof the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented new and usefulImprovements in Lamp-Holders, of which the following is a specification.

or object is to provide a ple, practical and readily adjustable electriclamp holder, and our invention consists of the novel featureshereinafter shown, described and claimed. a

Figure '1 is a side elevation showing a lamp holder embodying theprinciples of our invention supported on a wall.

Fig. 2 is a front end elevation looking in the direction indicated bythe arrow 2 in ig. 1, parts being broken away to show other parts.

Fig. 3 is a fragmentary top plan view as indicated by the arrow 3 inFig. 1.

Fig. 4 is a fragmentary side elevation analogous to Fig. l and showing amodified form of a supporting bracket.

Fig. 5 is a top plan view as indicated by the arrow 5 in Fig. 4.

Fig. 6 is a view analogous to Figs. 1 and 4, and showing a portablestand support in stead of the wall bracket shown in Fig. 1, or the postshown in Fig. 4.

ig. 7 is a view analogous to Fig. 3 and showing a modified construction.

Referring to Fig-s1, 2 and 3, an attaching plate 1 is adapted to fitagainst the flat face of a wall 2 and be secured in place by screws 3inserted through the plate into the wall. A vertical socket 4 extendsinwardly from the attaching plate 1, thus producing a wall bracket 5.lever 6 is mounted upon a pivot 7 in the socket 4 and in a slot 8, andthe lower end of the lever 6 swings into the socket opening 9. The upperend of the lever serves as a handle, and a spring 10 is secured to thesocket and engages the handle to throw the handle outwardly and thelower end inwardly to form a catch. The horizontal supporting arm 11 isformed integral with a vertical pintle 12, there being a shoulder 13 atthe upper end of the pintle 12 to fit upon the upper end of the socket4. and the pintle 12 fits rotatably in the opening 9. A recess 14 isformed in the pintle 12 to receive the catch formed by the lever 6, sothat when the pintle is shoved relatively simed upon the bolt to downinto the socket the catch will hold the pintle from being withdrawnuntil the upper part of the lever is operated to compress the spring 10and release the catch. A vertical bar 15 is rigid with the outer and ofthe arm 11 and extends up and down. A. for; 16 extends upwardly from thebar The lazy tong lever 17 is hingedly connected to the upper end of thebar 15 by a pin 18. The second lazy tong lever 19 has its lower endinserted through a vertical slot in the lower end of the bar 15, andpins 20 and 21 are fixed through the lower end upon opposite sides ofthe bar 15 so as to allow the bar to move up and down as required by thelazy tong action. The levers 17 and .19 are connected by a pivot 22. l

A plurality of lazy tong levers 23 are CO11-- nected to the lower end ofthe lever 17 and to the upper end of the lever 19 by pivots 24 and 25.vertical bar 26 is connected to the upper end of the last lazy tonglever 27 by a pivot 28, and the lower end of the last lazy tong lever 29extends through a vertical slot in the lower end of the bar 26, and pins30 and 31 are inserted through the lever 29 on opposite sides of the bar26 so as to allow the lever 29 to move up and down relative to the bar26 as required by the lazy tong action. A fork 32 extends upwardly fromthe bar 26, and with fork 16 forms a convenient support for the lampcord 33. A horizontal arm 34 extends forwardly from the center of thebar 26 and has abearing 35, said bearing 35 having a horizontal axis andthe end faces of the bearing being corrugated, the spring arms 36 and 37having bearings 38 and 39 fitting the corrugated faces upon the bearing35. A bolt 40 is inserted through the bearings 39, 35 and 38, and a wingnut 41 is screw seatclamp the bearings 38 and 39 against the bearing 35to hold the spring arms 36 and 37 in an adjusted position. The outerends 42 and 43 of the spring arms 36 and 37 are curved outwardly and thecentral portions 44 and 45 of the spring arms are concavo-convex, sothat the electric lamp socket 46 attached to the cord 33 may be passedbetween the ends 42 and 43 to the portions 44 and 45, and said portions44 and 45 will embrace the neck of the lamp socket and hold it inposition, as shown in F ig. 1. The spring arms 36 and 37 may be adjustedup and down by manipulating the wing nut 41' to tilt the lamp l7 to anydesired position. It is obvious that the lazy tong action will carry thelamp to and from the wall 2 to the limits of the action.

Referring to Figs. 4: and is mounted in clips 49 and a9 and 50 havesplit clamping bearings 51 and 52- adapted to enga e a vertical postlike a bed post 53, and the lazy tong construction shown in Fig. 1 maybe removed from the wall bracket and inserted into the socket l8 whendesired.

Referring to Fig. 6, the heavy stand base 5, the socket 48 1- has asocket- 55 extending upwardly from its center, a-ndthe lazy tongconstruc tion shown inv Fig. 1 may be removed. from the wall bracket 5,or from the bed' post bracket 56,'shown in Fig. 4, and inserted into thesocket 55. 7

Referring to Fig. 7 the lamp holding 'iork 57 has a'serew threaded stem58 reinovably screwed into a boss 59, and the boss carried by a barsimilar to the bar 26, thus making a rigid connection between the lamp60 and theilazy tong construction 50, and the clips instead of theadjustable joint shown in Fig. 3. V 7

Various changes may be made Without departing from the spirit of ourinvention as claimed.

\Ve claim: A lamp holder comprising a vertically disposed socket, aspring catch arranged thereon, a pintle journaled in said socket andprovided with an annular notch that is adapted to receive the point ofthe spring 7 catch, av vertically disposed bar connected to the upperportion of of lazy tong levers pivotally connected to said bar, avertically disposed bar piyotally connected to the outer end of the lazytongs,

a lamp supporting bracket pivotally con nected to the last mentioned barand forks projecting upwardly from said vertically disposed bar forsupporting the current carrying wires that extend to the lamp that ispositioned in said bracket. a In testimn'oy whereof we have signed ournames to this specification.
